Hi! Only Java because it's the language used in the courses. Also we use Java at work.
Kotlin is in my TODO list, I can't give my opinion yet. All my colleagues and friends praise it. When I saw a Kotlin demo at Google I/O I was impressed, so I'll definitely try it! :)

 

Nice! If I can offer some general advice, it would be to not to feel pressure to move to the new hotness. Learn Kotlin if it interests you but Java ain't going anywhere πŸ˜‹
